A new convergence criterion for nonlinear systems was recently derived by the first author. The criterion is similar to Lyapunov’s second theorem but differs in several respects. In particular, it has a remarkable convexity property in the context of control synthesis. While the set of control Lyapunov functions for a given system may not even be connected, the corresponding set of “density” funct

The modern requirements on power transmissions focus on energy efficiency, low noise and dynamic vibrations, and power density. In order to meet these requirements, the gear wheels must be manufactured to very high precision. Additionally, it should be economical to manufacture these gears within the tight requested tolerances. Gears manufactured within automotive, truck, and construction equipmen
I mitt pågående avhandlingsarbete om återvändande amerikaemigranter undersöker jag dels hur vistelsen i Amerika påverkat återvändarnas liv och dels hur återvändarna påverkade lokalsamhällena efter deras hemkomst till Sverige. Jag har avgränsat mitt undersökningsområde till sex församlingar i nordvästra Skåne och till perioden 1870-1930. Mina tidigare undersökningar har visat att återvändarna i mit
The Second String Quartet by Arnold Schoenberg, written in 1907 and 1908, is breaking musical traditions at least twice – (1) by leaving tonality, (2) by breaking the genre of string quartet, adding a voice who is interpreting two poems by the German symbolist Stefan George in its third and forth movements. In this paper, I want to raise the question about the reasons why Schoenberg might have add
Software engineering consists to a large extent of management of information. A qualitative survey on information management in software development companies has been conducted. The survey studies how the companies work with different kinds of documents, which notations are used, quality of the documents etc. The focus is on high-level documents, such as requirements specifications and system tes
